Description

本考案は、主としてサラダ菜、レタスやサンチュのような葉物野菜等のような軽量物を梱包するのに好適な梱包用段ボール箱に関するものである。   The present invention mainly relates to a packaging cardboard box suitable for packaging lightweight items such as salad vegetables, leafy vegetables such as lettuce and sanchu.

物品の梱包に段ボール箱が用いられているが、段ボール箱は一般的に、内部に物品を収容した後、左右の蓋部分の合わせ部をテープで貼着し、閉蓋状態を保持するように設定されている。
この場合、段ボール箱を開梱するには、貼着したテープを剥がす作業を必要とし、作業が面倒、煩雑であること、テープを剥離する過程で段ボール箱のテープ貼着部の表面組織が剥がれ、段ボール箱が損壊する等の事態が発生し、段ボール箱を傷つけることなく再使用することが難しく、経済的な点においても不利である。
Corrugated cardboard boxes are used for packing goods, but generally, cardboard boxes are used to hold articles in the interior, and then stick the mating part of the left and right lid parts with tape to keep the lid closed. Is set.
In this case, in order to unpack the cardboard box, it is necessary to remove the attached tape. The work is cumbersome and complicated, and the surface structure of the tape attachment part of the cardboard box is peeled off in the process of peeling the tape. The cardboard box is damaged, and it is difficult to reuse the cardboard box without damaging the cardboard box, which is disadvantageous from an economical point of view.

従来、段ボール箱の開梱を容易化する考案が知られている(例えば、特許文献1参照。)。
登録実用新案第3019071号公報
Conventionally, a device for facilitating unpacking of a cardboard box is known (for example, see Patent Document 1).
Registered Utility Model No. 3019071

特許文献1の考案は、立方体からなる梱包用段ボール箱10(同公報中の符号を用いる。以下同じ)の上面から前面にかけて蓋部15を切り離す破断状切込部16を連続して形成し、破断状切込部16は、段ボール箱10の前面上端寄りに延在し、終端部を傾斜させて破断状傾斜切込部16Aを形成し、破断状傾斜切込部16Aの両下端を水平な差込孔17で繋げて設けてあり、蓋部を切り離す際、破断状傾斜切込部16Aとの境界部分引張力が集中的に加わり、蓋部15が破断状傾斜切込部16Aに沿って切り離すことができる構成である。
蓋部15を切り離すと、段ボール箱10の上面から前面に跨る広い取出口25を開けることができるものである。
The device of Patent Document 1 continuously forms a breakable cut portion 16 that separates the lid portion 15 from the upper surface to the front surface of a packaging cardboard box 10 made of a cube (the reference numeral in the same publication is used hereinafter). The breakable notch 16 extends near the upper front end of the corrugated cardboard box 10, the end portion is inclined to form a breakable inclined notch 16 </ b> A, and both lower ends of the breakable inclined notch 16 </ b> A are horizontal. When the lid is cut off, the boundary portion tensile force with the breaking inclined notch 16A is applied intensively, and the lid 15 extends along the breaking inclined notch 16A. It is a configuration that can be separated.
When the lid 15 is separated, a wide outlet 25 extending from the upper surface to the front surface of the cardboard box 10 can be opened.

以上の特許文献1の考案では、1回の操作で段ボール箱の蓋部を開き、開口面積の広い取出口を開口することができるが、段ボール箱から蓋部を切り離す作業が必要であり、開梱作業性の点で面倒、煩雑であり、開梱作業がしづらいこと、蓋部を段ボール箱の前面、上面から切り離して開梱するので、開梱により開口面積の大きな取出口は形成し得るが、開梱後の蓋片を含む段ボール箱は再使用ができず、開梱後の段ボール箱は廃棄せざるを得ず、経済的なデメリットが大きい。
本考案は、以上の問題点を解決すべくなされたものである。
